Minimum Trigger Period Setting Calculation Formula
[Unit：us]
Maximum USB Bandwidth is;
[USB Limit] = 5120 x 3840 x 8bit x 16.00 fps = 2516582400 bps
Data Rate by ROI setting is:
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 641) + 38580) ÷ 40MHz) x 1.25
As comparing [USB Limit] and [USB Rate]
(1) IF [USB Limit] < [USB Rate]
[Readout Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8 ÷ 1.25
(2) IF [USB Limit] > [USB Rate]
[Readout Rate] = 1/((([Height] x 641) + 38580) ÷ 40MHz)
[Trigger Period] = (1/ [Readout Rate])+[Exposure Time:10us ~8s]
+ 16.025 us
Data Rate by ROI setting is:
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 1282) + 38580) ÷ 40MHz) x 1.25
As comparing [USB Limit] and [USB Rate]
(1) IF [USB Limit] < [USB Rate]
[Readout Rate] = [USB Limit] ÷ [Width] ÷ ([Height] x 2) ÷ 8 ÷ 1.25
(3) IF [USB Limit] > [USB Rate]
[Readout Rate] = 1/((([Height] x 1282) + 38580) ÷ 40MHz)
[Trigger Period] = (1/ [Readout Rate]) + [Exposure Time:10us ~8s]

As comparing [USB Limit] and [USB Rate]
(1) IF [USB Limit] < [USB Rate]
[Readout Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8 ÷ 1.5
